Abstract: ABSTRACT OF THE DISCLOSURE           Toughened multi-phase thermoplastic composition consisting essentially of one phase containing 60 to 99 percent by weight of a polyester including polycarbonate matrix resin of inherent viscosity of at least 0.35 deciliter/gram, and 1 to 40 percent by weight of at least one other phase containing particles of at least one random copolymer having a particle size in the range of 0.01 to 3.0 microns and being adhered to the polyester, the at least one random copolymer having a tensile modulus in the range of 1.0 to 50,000 p.s.i., the ratio of the tensile modulus of the polyester matrix resin to tensile modulus of said at least one polymer being greater than 10 to 1.  Said at least one polymer is either a branched or straight chain polymer.  The toughened compositions are useful for making molded and extruded parts.  Such parts possess greater ductility, less reduction in toughness from scratches and molded-in notches and reduced susceptibility to catastrophic failure when compared to known melt fabricated materials.

Abstract: PROCESS FOR THE CONTINUOUS MANUFACTURE OF O- AND P-CHLOROTOLUENE         Abstract of the disclosure: o- and p-chlorotoluene is obtained at practically quantitative yields and excellent quality by continuous chlorination of toluene at a molar number ratio of chlorine to toluene of about 0.4 to 1 and at a temperature of about 5 -70°C, in the presence of at least one catalyst being known for such nuclear chlorination reactions, in a parallel current while mixing thoroughly; after completion of the reaction the reaction mixture is freed by distillation from hydrochloric acid and from non-reacted toluene, and the remaining distillation residue is separated immediately to yield the isomeric o- and p-chlorotoluenes.     Side-chain chlorination is practically avoided at all by this process, so that cumbersome purification operations such as the removal of chlorine linked to the side chain by boiling under pressure with alkali base may be dispensed with. The chlorotoluenes are partially utilized as solvents, partially as intermediate products e.g. for the manufacture of plant protection agents.

Abstract: MULTILAYER CIRCUIT BOARD WITH INTEGRAL FLEXIBLE APPENDAGES            ABSTRACT OF THE DISCLOSURE         Novel method and apparatus for creating multilayer printed circuit boards having integral flexible conductor appendages, involving the utilization of an array of flexible, circuit-containing layers bonded in properly aligned rela-tionship between rigid layers equipped with suitable elec-trical connections.  In accordance with this invention, all of the aforementioned layers are substantially larger than the size the finished circuit board is to be, thereby making possible, in accordance with this invention, the creation of integral, flexible appendages to the circuit board.  The assemblage of layers if maintained in this over-sized condition throughout the procedure in which holes to be used for interconnections are drilled, and quite importantly, during the time these holes are being plated through with conductive material.  Only after the plating procedure has been completed are the portions of the upper and lower rigid layers removed from locations above and below the appendage portions, thus allowing them to attain the desired, flexible condition.  The important advantage gained by utilizing the rigid material on the appendage portions is that by maintaining such portions of the assemblage rigid during the plating procedure, undesirable work hardening of the flexible portions is avoided, without tools for restraining the flexible portions having been necessary.    Subsequent removal of the rigid material was selectively withheld from certain portions of the assemblage at the time bonding was being accomplished, and the rigid material was slotted in pre-established locations.

Abstract: ABSTRACT:          Cushion-like and barrel-like frame distortions can be corrected for by generating in the system of deflection coils of a black-and-white or colour display tube a static eight-pole field the poles of which are situated betwenn the axes of a system of axes the directions of which of the axes alternately coincide and extend diagonally with the two directions of deflection.  In colour display tubes the eight-pole field is preferably situated on the side of the display screen of the system of deflection coils so as to minimize the influence on the convergence.  The influence on the convergence can be eliminated substantially by incorporating a second eight-pole of opposite polarity on the gun side of the system of deflection coils.

Abstract: ABSTRACT A method and apparatus is disclosed for use in per-forming automated classification of cells of a pap smear as well as other types of cells, such as red blood cells and blood cell neutrophiles.  The apparatus generates an image that is split into two paths, 1) a high resolution image of primarily the nucleus of a cell, and 2) a low resolution image of the total cell, nucleus and cytoplasm.  An image scanning device located in the first path provides output signals representing the image and circuitry performs measurement and analysis relating to texture of the nucleus.  The image in the other path is demag-nified which provides an enlarged, lower resolution image of the entire cell, including the nucleus and the cytoplasm and it is projected to a second image scanning device, which provides electrical signals that represent the image of the larger area and circuitry performs measurement and analysis relating to the size, density and color of the cytoplasm and the nucleus.  The analysis obtained from each of the two circuits are applied to classification logic circuitry for the purpose of determining malignant cells.
